I wear slippers all the time indoors, and in the garden when it's not wet - but my feet are painful all the time (even in the slippers). I buy mine from "Pavers" because I take a wide fitting size 2. This size is not available from high street stores, or indeed from many manufacturers at all. Children's slippers are too narrow. Hard floors hurt my feet, but because we have two cats, only the living room has carpet. Laminate floors everywhere else for ease of cleaning!
